SPECIFICATION formingpart of Letters Application filed April 8, 1884.

T0 aZZ whom it may concern.-

Be it known that I, GORDON EARL, a citizen of the United States, residing at Pierson, in the county of Montcalm and State of Michigan, have invented certain new anduseful Improvev ments in Shingle-lilachines, of which the following is a specification.

My invention relates to the arrangement of friction-rollers in connection with the ways of the tilting table of a shingle-machine; and the object of my invention is to lessen the friction between the shingle-bolt and the ways when the bolt is pushed forward against the erator.- This object 1 accomplish by the mechanism illustrated inthe accompanying drawings, in which Figure 1 is a plan view of a tilting table saw and a portion of the frame of a shinglemaohine to which my invention is applied. Fig. 2 is a side view of atilting table, showing one of the ways with friction-rollers attached thereto; and Fig. 3 is a sectional view of the tilting table on line at m of Fig. 1.

Similar letters refer to similar parts throughout the several views.

In the drawings, A represents the saw; B and B, the end supports of the tilting table, which tilts or oscillates on journals 0 G in the ordinary manner, F and F being journalboxes in B and B. O and C are attached to the frame D, as shown in Fig. 1. E and E are the ways attached to the end pieces, B and B, and with such end pieces form the tilting The frame D is supported by the main table.

, rollers, as above described.

The operation of my invention is as follows: The shingle-bolt being placed in the carriage, it rests on the friction-rollers, and as the carriage is pressed forward the bolt rides on the rollers until the shingle is cut by the saw from the bolt. The carriage is now drawn back, the bolt passing above but not in contact with the rollers. When the carriage has been drawn back, the bolt again drops onto the rollers and is again pressed forward onto the saw.

Having thus described my invention, what I claim to have invented, and desire to secure by Letters Patent, is

In a shingle-machine, the combination of the series of friction-rollers a a a a, turning on journals 0 c c 0, the side pieces, E and E, end pieces, B and B, and journals 0 and 0, all substantially as and for the purpose described.

GORDON EARL.
